A 100 g ball is thrown upwards with an initial velocity of 20 m/s. What is its kinetic energy at the highest point?
Q1. A 100 g ball is thrown upwards with an initial velocity of 20 m/s. What is its kinetic energy at the highest point?
Answer: 0 J
Explanation: At the highest point, velocity = 0, so KE = 0. Option B fails because it assumes some velocity remains.
